According to the experiments and observations of specialists, new discs bend from the blow noticeably less than the discs after repair.

For example, a renovated disk is obliged to withstand a blow of four hundred kilograms, at an angle of about 30 degrees, this is if you crash into a bard of 60 kilometers per hour.

The most dangerous in the disk after repair is that its destruction can occur at any time, even in the most not predictable.

If you turn to logic, you can understand that with any intervention in the structure of the disk, its base will no longer be perfect.

Well, in fact, only in 1964 such discs began to be produced for serial cars.

For racing cars, they tried to use the lighter material, that is, aluminum, the idea failed, since it was not strong enough.

They were replaced by the idea of ​​German engineers who suggested making wheels from a steel plate.

The first car discs were made of ordinary knitting needles, as now on bicycles.

And of course, the third option is forged, are considered the best because they combine all the best qualities above the above discs, but there is one not big minus — at the price are considered the most expensive.

There are three types of wheels, and this is a steel stamping, this is a very heavy and quite strong disk, it is considered one of the cheapest.
